Rice University offers a number of web and iPad-based educational science activities for students of all ages. Germ Blaster is one of their free iPad games that is appropriate for students in elementary school.
Germ Blaster is a fun iPad game through which students learn about six types of pathogens and the “weapons” used to fight them. Before starting the game students review each pathogen and what makes it different from the others. Then they review the methods used to fight those pathogens. In the Germ Blaster game students fight off the pathogens by selecting the appropriate weapon to kill the approaching pathogens. If they get stuck and can’t remember which weapons fight which pathogens, students can pause the game to look up information about the pathogens.
Applications for Education
Playing Germ Blaster won't replace the need for lessons taught by you, but it could be a fun way for students to review after a lesson that you have taught.
